Likely a stupid question but I'm a touch of a hypochondriac so these sorts of things occur to me. Could dimethylmercury be produced at home by accident? Like could it inadvertently be created? I live in a house built in the 40's and the fixtures are as old, including the bathroom mirror. Apparently old mirrors could have mercury amalgam in them, could cleaning them with the wrong thing produce a reaction that would create that dimethylmercury? I know something about halides is involved in making dimethylmercury and one of the cleaners I use to clean my mirror has magnesium chloride in it, which is a halide right? If there were mercury in the mirror could it react and produce dimethylmercury? Or does the production of such a thing require a more intricate process, heat, pressure, other chemicals, etc? I watched a YouTube video about a scientist who died of dimethylmercury poisoning, and it kind of spooked me.
